Rely on the group’s macro fluid motion of the heat transfer. This is heat transfer of the three basic means.
Chemical production processing materials is fluid, most of the fluid of heating and cooling include convection heat transfer. In the chemical production, convection heat transfer in the custom fluid and temperature in different points to the fluid solid wall of direct contact between when heat transfer.
This is actually a spread of heat and heat conduction two basic way of heat the interaction of heat transfer process.
For example the mural type heat exchanger between fluid and JianBi side of heat transfer between the reactor, the solid materials or catalyst and fluid of heat transfer between, that this is the heat transfer process.
